Title: All-speed govenor for gas turbine engines
IPC: F02C9/28
Filed: 1952-12-01
Abstract: 716,415. Speed governors. BENDIX AVIATION CORPORATION. Dec. 1, 1952 [Dec. 26, 1951], No. 30445/52. Class 57 A speed governor system for an engine comprises a resettable governor 48 connected to a valve 44 which controls a fuel restriction 43 and is associated with springs 51, 52 adjustable to vary the setting of the governor, means being provided for effecting a balance between the springs during equilibrium operation of the system. This means consists of a dashpot piston 49 the position of which is controlled by a piston 53 and a lever 54 in accordance with the required setting of the governor. The restriction 43 is connected to an annular chamber 67 fed with fuel from a duct 42 in communication with a chamber 11 in which the pressure is controlled by a regulating valve 14 coupled to a spring-loaded diaphragm 13 and a second governor 33. When a variation in engine speed causes a movement of the valve 44 the resultant pressure fluctuation in the chamber 11 is compensated by the governor 33 displacing the regulating valve 14. The latter is supplied from a duct 18<SP>1</SP> containing a fuel pump 19, the pressure in this duct being controlled at a set value above the pressure in a duct 68 supplying the engine by a by-pass valve 21 and a spring-loaded diaphragm 26. A relief valve 32 is also provided. When it is required to increase engine speed, the dashpot 49 is moved to the right whereupon the valve 44 moves to its fully open position until the governor 48 has acquired sufficient speed to move it to its new equilibrium position. This closing action of the valve occurs too rapidly to permit the dashpot piston 49 to move and consequently is opposed only by the spring 51 which provides greater resistance to the movement of the valve than the combined effect of the springs 51, 52 so that the engine overshoots the new required speed until the dashpot has moved to its new equilibrium position with the springs 51, 52 in balance. To avoid this overshoot, the pressure on the left hand side of the dashpot piston may be reduced when the engine accelerates by a double headed piston 60 mounted in a chamber 62 connected by ducts 64, 65 with the dashpot and a chamber 41<SP>11</SP> containing an impeller 66. Acceleration of the latter by the engine displaces the piston 60 to the right to draw fluid through the duct 64 from the. dashpot. The system is particularly applicable to aircraft turbine engines and includes a supplementary fuel duct 71 controlled by an aneroid in spring-loaded bellows 75 to compensate for variation in the density of the air intake. Specifications 604,466, 612,840, 634,095 and 655,311 are referred to.

[Class 56] [Also in Group XI] Glass fibres are made by drawing thin streams of molten glass downwardly from the ends of a number of pointed teeth formed on a refractory comb-like member over which the glass flows, the toothed portion being heated from a source of heat other than that of the molten glass. The member 13, Fig. 2, made of platinum or other refractory metal, may be supported in a furnace forehearth 11 with the teeth 15 extending through a slot 12 in the floor of the forehearth. The glass flowing from the points of the teeth is drawn into threads by a blower 20, as described in Specification 428,720. The member 13 is heated by the passage of an electric current, and the heating may be assisted by the flames from gas burners 21. Another method of heating by electricity consists of making the two sides 33, 34, Fig. 5, of the blower separate from one another and impressing on them the output of a high-frequency oscillator 30 so as to generate heat by dielectric losses within the glass. The comb may consist of a metal member 26 attached to a block 23 of refractory material: the block is housed within a heated casing 25, and the glass flows into shallow pockets 24, formed on the shoulders of the block, whence it flows down the sides of the block.
